HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 748,803, dated January 5, 1904.

.To @ZZ whom it may concern:

Be it known that I, JEROME T. SMITH, a citizen of the United States, residing at Scotland,

in the countyof Bonhomme and State of South Dakota,baveinvented a new and useful Heating-Stove, of which the following is a specication.

This invention relates to heating-stoves; and it has for its object to provide a stove of great simplicity of construction andin which provision shall be made for the circulation within the stove-casing of air to be heated during its passage through the conduits provided for that purpose.

My invention consists in the improved construction, arrangement, and combination of parts tending to produce a device of the class described which shall possess superior advantages in point of simplicity, durability, and general efticiency, as will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of a stove constructed in accordance with the principles of my invention. Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. 1.

Corresponding parts in botligures are indic-ated by similar numerals of reference.

1 designates the base of the stove, which simply constitutes an ash-pit of large capacity and which is provided with a door 2, having a damper, as is usually the case, for the purpose of regulating the draft. The base 1 supports a grate 4 and a ire-pot 5, whichlatter is preferably cylindrical in shape and is provided near its lower end with an opening 6. The base 1 is provided with an annular flange or odset 7 at its upper edge, which serves interiorly to support the grate and {ire-pot. Exteriorly the said oiset supports a base-plate 8, which extends beyond the outer curved portion of the base, so as to form an annular angular recess 9, which extends circumfereutially between the base 1 and the base-plate 8.

10 designates an annular top plate, and 11 a cylindrical casing, usually of sheet metal, which separates the base-plate 8 and top plate 10, said base and .top plates being connected in the usual manner by stove-rods or other suitable means. (Not indicated in the drawings.) The annular top' plate 10 is formed with'a dome 12, having a danged opening 13,

(which supports a smoke-exit pipe 14.

The top and bottom plates 10 and 8 are each provided with an annular series of perforations 15, which are connected by means of pipes 16. The perfor-ations 15 are disposed at such a Ydistance from the outer edges of said plates that the lower or intake ends of the pipes 16 shall communicate with the an- 'nular space 9 between the -plate Sand the base of the stove. It follows that air entering the lower ends of the pipes will be already heated by contact with the exterior'v surface of the base, and an upward draft or suction will thus be created which will be effective in causing a rapid and thorough circulation of air through the pipes 16.

Suitably connected with the dome 12 of the top plate 10 by means of straps 17 or equivalent devices is a tank 1S, which hasa funnelshaped lower end 19, disposed directly above the tire-pot and serving to deflect the products'of combustion outwardly in the direction of the air-pipes 16, causing the latter to be completely enveloped by the flames arising from the gases that are being consumed and likewise by the products of combustion which are ascending toward the exit-pipe 14. The tank 18, which is composed of refractory metal, may serve simply as a radiator` and air-heater, and it is provided with pipes 20 and 2l nearits lower and upperends, through one of which air may be admitted into the tank and from the other one of which the 'heated air may be conducted to apartments The tank 18,

that it may be desired to heat. however, may he equally well utilized as a water-heater, as will be readily understood. The lower end of the stove-casing is provided with a door 22, alining with the opening 6 in the tire-poaand through 1whichcaccess may be had to the latter for the purpose of raking the fire.

For the purpose of feeding the tire the casing is provided with a door 23, alining with the space between the lire-pot and the Ylower end of the tank 18. From the pipes 16, which are located between the door and the fire-pot, sections are removed in order to admit of the IOO passage of fuel into the re-pot, and for the purpose of not impairing the continuity of the pipes these sections, which have been designated 24, are suitably mounted or secured in the door in alinement with the adjacent ends of the pipes which have been thus severed. In order to admit of this construction, the door 23 is provided with top and bottom plates 25, with which the ends of the intermediate pipe-sections are connected, it being obvious, however, that it is not necessary that the identical pieces removed from the pipes 16 should be thus located, but that the door may be formed as a casting containing connecting pipe-sections adapted to aline with the pipes 16, from which intermediate sections have been removed. Suitable connecting means, as 26, are also provided for the purpose of connecting the severed ends of the pipes 16, thereby holding them in alinement with the pipe-sections in the door when the latter is closed.

From the foregoing description, taken in connection with the drawings hereto annexed,

the operation and advantages of my invention will be readily understood. It will be observed that the casing of the stove supports an unbroken annular series of air-circulating pipes, through which constant and rapid circulation and heating of air will take place. When the feed-door is temporarily opened for the purpose of feeding the tire, the coal or other fuel used may be readily thrown into the {ire-pot, the pipe-sections above and below the door offering no hindrance. As soon asV the door is closed the said pipe-sections are connected by the pipe-sections extending vertically through the door, as described.

The general construction of my improved stove is simple and eective. Its heating capacity is equal to that of other and more complicated stove structures, and it may be constructed at a moderate expense. The fact should also not be lost sight of that the heating-tank within the stove, whether used simply as a radiator, an air-heater, or a waterheater, is a valuable adjunct to the stove, serving to assist in extracting and utilizing all the heat units that may be developed by the fuel consumed.

Having thus described my invention, I claim- 1. In a stove, a base forming an ash-pit and having a flanged o'set, a grate and fire-pot supported interiorly upon the latter, an annular base-plate supported exteriorly upon said offset,a top plate having a dome provided with a smoke-exit, a cylindrical casing spacing the top plate and the base-plate, a plurality of air-circulating pipes connecting the top plate and the base-plate, and a tank suspended by straps-from the dome of the top plate, said tank being surrounded by the aircirculating pipes and terminatingin afunnelshaped bottom above the re-pot.

2. In a stove of the class described, the combination of a base constituting an ash-pit and having an annular ange or olset,a grate and re-pot supported interiorly upon said offset, a base-plate supported exteriorly upon said oiiz'set and extending over the curved outer walls of the ash-pit, a top plate, a cylindrical casing spacing the latter and the baseplate, air-circulating pipes connecting the base and top plates, several of said pipes being separated at an intermediate point, and a stove-door hinged to the casing and having intermediate pipe-sections which, when the stove-door is closed, are in alinement with and serving to connect theends of the separated pipes.

3. In a stove, an annular series of vertically-disposed circulating-pipes and a casing havinga feed-door, the circulating-pipes alining with said feed-door having sections removed therefrom, of a length equal to the height of the feed-door, the opposing ends of the several pipes thus severed being suitably connected and braced, in combination with corresponding pipe-sections extending vertically through the feed-door and alining, when the latter is closed, with the adjacent ends of the severed air-circulating pipes.

In testimony that I claim the foregoing as my own I have hereto axed my signature in the presence of two witnesses.

JEROME T. SMITH.
